HST5330U Transformer Protection and Monitoring Device
Application Scope
The HST5330U Transformer Protection and Control Device is suitable for the protection and monitoring of station transformers or grounding transformers in substations of 3～35kV voltage level. It can be installed locally on switchgears in a distributed manner or centrally in panels. Equipped with communication interfaces, it can form an automation system together with other protection and automation devices via communication links.
